Description
Technical Field
[0001] This invention belongs to the technical field of railway catenary construction equipment, specifically a railway catenary H-shaped column installation clamp. Background Technology
[0002] The overhead contact system is a crucial overhead equipment in electrified railways and urban rail transit systems, providing continuous power transmission to electric locomotives or EMUs. The contact system supports, primarily H-shaped columns, serve as its core support structure, and their installation quality directly affects the stability and operational safety of the contact system. Traditional column installation mainly relies on large lifting machinery combined with manual labor, which has the following significant drawbacks.
[0003] The hoisting and posture adjustment of columns, from horizontal transportation to vertical installation and alignment, are mostly completed through crane operation and ground personnel command and assistance. This requires a large number of personnel, is labor-intensive, and the installation accuracy is greatly affected by the experience of the personnel. Cement columns are usually conical, while steel columns are mostly pyramidal. Traditional wire ropes or simple lifting tools are difficult to achieve stable and self-adaptive clamping. For columns with different cross-sectional shapes and sizes, lifting tools often need to be changed or adjusted, which is inefficient and poses a risk of slippage. Precisely inserting the lower end of the column into the pre-embedded foundation or aligning it with the installation position mainly relies on the large-scale movement of the robotic arm and manual fine-tuning. The process is cumbersome and time-consuming. Especially for scenarios that require precise control of insertion depth and verticality, traditional methods are difficult to achieve stable and controllable precise lowering. During the hoisting and flipping of columns, relying on only a single lifting point or simple clamping method, the column is prone to shaking or even rotation, posing a safety hazard. There is a lack of a multi-level, multi-point stabilization mechanism for the column during hoisting.
[0004] To overcome the above problems, it is particularly necessary to develop a special device that can be integrated into excavators to achieve automated clamping, flipping, precise alignment and installation. Although there are some lifting or clamping devices for columnar objects in the existing technology, they are often single in function or cannot be compatible with two different materials, cement and steel, and there is a lack of comprehensive solutions that integrate clamping, flipping, fine-tuning alignment and controllable pressing installation.
[0005] Therefore, there is an urgent need to design a new type of H-shaped column installation clamp for railway catenary. It should be able to quickly and stably clamp conical columns of different materials, realize automatic flipping from horizontal to vertical posture, and make fine adjustments to the axial position and controllable pressing during the installation stage, thereby improving the automation level, operation accuracy, safety and overall efficiency of catenary column installation. Summary of the Invention
[0006] To solve the above problems, the present invention provides an H-shaped column mounting clamp for railway catenary.
[0007] This invention adopts the following technical solution: a railway catenary H-type post mounting clamp, comprising: The picking mechanism is used to clamp and pick up the H-shaped column, and the picking mechanism includes: A main clamping frame, on which a connecting end block for connecting with the excavator's robotic arm is rotatably mounted, a central gear is fixedly mounted on the main clamping frame, a rotary motor is fixedly mounted inside the connecting end block, and a motor gear that meshes with the central gear is fixedly mounted on the motor shaft of the rotary motor; Two sets of gripper modules are symmetrically arranged on the main clamping frame. Each gripper module includes an extension cylinder fixedly installed on the main clamping frame. An extension gripper frame is fixedly installed at the output end of the extension cylinder. Two gripping grippers are rotatably installed on the extension gripper frame. Two adjustment mechanisms are provided. The adjustment mechanisms are used to fine-tune the axial position of the H-shaped column. The adjustment mechanism includes a guide clamp fixedly installed on the main clamping frame. A lifting screw is rotatably installed on the guide clamp. The lifting screw is provided with two external threads with opposite thread directions. Lifting clamp blocks are respectively connected to the two external threads. An adjustment roller is rotatably installed on each lifting clamp block. Two stabilizing mechanisms are used to prevent the H-shaped column from slipping out. Each stabilizing mechanism includes two fixed rotating blocks that are fixedly mounted on the main clamping frame. A rotating clamp is rotatably mounted on each fixed rotating block, and a clamping roller is rotatably mounted on the rotating clamp.
[0008] In some embodiments, a brake disc is also fixedly mounted on the main clamping frame. The brake disc is located outside the central gear. An inner brake is provided inside the connecting end block. The inner brake is located next to the brake disc. The inner brake cooperates with the brake disc to lock the relative rotational position of the main clamping frame and the connecting end block.
[0009] In some embodiments, a side guide block is fixedly installed on the extended claw frame, an inner movable block is slidably installed inside the side guide block, and a clamping cylinder is fixedly installed on the inner movable block. The clamping cylinder is provided with two output ends, and the output ends of the clamping cylinder are rotatably installed with the clamping claw.
[0010] In some embodiments, the clamping cylinder is provided with inlet and outlet oil pipes, which are connected to the hydraulic system of the excavator.
[0011] In some embodiments, a lifting motor is fixedly installed on the guide clamp, an output gear is fixedly installed on the motor shaft of the lifting motor, and a lead screw gear that meshes with the output gear is fixedly installed on the lifting lead screw.
[0012] In some embodiments, an adjusting motor is fixedly installed on the lifting clamp block, an adjusting gear is fixedly installed on the motor shaft of the adjusting motor, a rotating roller gear that meshes with the adjusting gear is fixedly installed on the adjusting roller, and an outer rubber sleeve is fitted on the outer side of the adjusting roller.
[0013] In some embodiments, a rotating frame gear is fixedly mounted on the rotating clamp, a clamping motor is fixedly mounted on the fixed rotating block, and a clamping gear that meshes with the rotating frame gear is fixedly mounted on the motor shaft of the clamping motor.
[0014] In some embodiments, an outer friction sleeve is provided on the outer side of the clamping roller.
[0015] In some embodiments, the upper and lower surfaces of the clamping claws are provided with slopes that adapt to the conical surface of the cement column and the pyramidal surface of the steel column.
[0016] In some embodiments, the two sets of gripper modules are arranged symmetrically along the central axis of the main gripper frame, and the two adjustment mechanisms and the two stabilizing mechanisms are distributed in a cross shape along the circumference of the main gripper frame, with the gripping direction of the adjustment mechanism perpendicular to the gripping direction of the gripper module.
[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) This invention integrates clamping, flipping, fine-tuning and installation functions, and can be directly adapted to excavators. Through the coordinated control of the motor and hydraulic system, the entire process of the column is realized from horizontal grabbing, flipping 90 degrees in the air to vertical state, and then to precise alignment and controllable downward pressure installation, which shortens the installation cycle of a single column and reduces the safety risks of manual operation under heavy components. (2) The picking mechanism of the present invention adopts a double gripper module. The gripper driven by the hydraulic cylinder has a slope at the end, which can adapt to the side shape of cement columns and steel columns with different tapers to achieve stable gripping. The adjustment mechanism and the stabilizing mechanism form additional, adjustable clamping and friction fixation on the column from different heights and directions through the adjustment roller with an outer rubber sleeve and the gripping roller with an outer friction sleeve. Through the multi-level clamping mode, the column is effectively prevented from shaking, rotating or slipping during hoisting and flipping, which enhances the stability and safety of the operation process. (3) The adjustment mechanism set in this invention plays a core role in the column positioning stage. By driving the bidirectional lead screw through the lifting motor, the two adjustment rollers can be controlled simultaneously to make radial centering fine adjustments to the column. Subsequently, the adjustment motor drives the outer rubber sleeve to rotate actively, generating downward friction force, thereby controlling and smoothly pressing the column down into the foundation. This process can accurately control the sinking speed and verticality of the column. With the follow-up fine adjustment of the lifting motor, it overcomes the problem of traditional hoisting which makes it difficult to accurately control the implantation process, and ensures the verticality, insertion depth and positioning accuracy of the column installation.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example: Reference Figures 1-10 A railway catenary H-type column installation clamp includes a holding mechanism for clamping and holding a cement column 4 and a steel column 5. The holding mechanism includes a main clamping frame 101. The holding mechanism is provided with two adjustment mechanisms for fine-tuning the axial position of the cement column 4 and the steel column 5 and two stabilizing mechanisms for stabilizing the cement column 4 and the steel column 5 to prevent them from falling out.
[0021] like Figures 3-5 As shown, the picking mechanism includes a central gear 112 and a brake disc 113 fixedly mounted on the main clamping frame 101. The brake disc 113 is located outside the central gear 112. A connecting end block 102 is rotatably mounted on the main clamping frame 101. A rotating motor 110 is fixedly mounted inside the connecting end block 102. A motor gear 111 is fixedly mounted on the motor shaft of the rotating motor 110. The motor gear 111 meshes with the central gear 112. An inner brake 114 is provided inside the connecting end block 102. The inner brake 114 is located next to the brake disc 113. The connecting end block 102 is mounted on the excavator's robotic arm.
[0022] like Figures 3-5 As shown, the picking mechanism also includes two gripper modules disposed on the connecting end block 102. The gripper module includes an extension cylinder 103 fixedly mounted on the main gripper frame 101. An extension claw frame 104 is fixedly mounted on the output end of the extension cylinder 103. Two gripping claws 109 are rotatably mounted on the extension claw frame 104. Both the upper and lower surfaces of the gripping claws 109 are provided with slopes.
[0023] like Figures 3-5 As shown, the gripper module also includes a side guide block 105 fixedly installed on the extended gripper frame 104. An inner movable block 106 is slidably installed inside the side guide block 105. A clamping cylinder 107 is fixedly installed on the inner movable block 106. The clamping cylinder 107 has two output ends. The output ends of the clamping cylinder 107 are rotatably installed with the clamping gripper 109. The clamping cylinder 107 is provided with an inlet and outlet oil pipe 108, which is connected to the hydraulic system of the excavator.
[0024] In use, the connecting end block 102 is installed at the end of the excavator's robotic arm. The inlet and outlet oil pipes 108 and the extension cylinder 103 are connected to the excavator's hydraulic system, and power is drawn from the excavator. First, the excavator moves to the side of the truck with the H-shaped column, which is in a flat position. The excavator uses its robotic arm to move the connecting end block 102 and the main clamping frame 101 to the side of the flat H-shaped column. Then, the two output ends of the clamping cylinders 107 of the two gripper modules retract, causing the inner side of the gripping jaw 109 to move inward. The inner movable block 106 slides along the side guide block 105, causing the gripping jaw 109 to open. Then, the extension cylinder 103 extends. The extension claw frame 104 and the clamping claws 109 move outward, so that the outer ends of the two clamping claws 109 reach the outside of the H-shaped column. Then, the two output ends of the clamping cylinder 107 extend, causing the outer ends of the clamping claws 109 to move inward, so that the two clamping claws 109 clamp the H-shaped column. Since the sides of the cement column 4 and the steel column 5 are conical and pyramidal surfaces, the two claw modules clamp the cement column 4 and the steel column 5 at two points to ensure the stability of the clamping. Since the sides of the cement column 4 and the steel column 5 are conical surfaces, the opening and closing degrees of the clamping claws 109 of the two claw modules are not the same.
[0025] After the H-shaped column is clamped by the gripper module, the excavator's robotic arm lifts the H-shaped column from the truck. The excavator then moves the H-shaped column to the installation site. The inner brake 114, which is in a locked state, is then activated, allowing the brake disc 113 to rotate. The rotating motor 110 drives the motor gear 111 to rotate, which in turn drives the center gear 112, the brake disc 113, and the main clamping frame 101 to rotate 90 degrees, making the H-shaped column vertical. The inner brake 114 then locks the brake disc 113 again.
[0026] like Figures 6-8 As shown, the adjustment mechanism includes a guide clamp 201 fixedly mounted on the main clamp 101, a lifting motor 202 fixedly mounted on the guide clamp 201, an output gear 203 fixedly mounted on the motor shaft of the lifting motor 202, a lifting screw 204 rotatably mounted on the guide clamp 201, the lifting screw 204 is provided with two external threads with opposite thread directions, a screw gear 205 fixedly mounted on the lifting screw 204, and the screw gear 205 meshes with the output gear 203.
[0027] like Figures 6-8As shown, the adjustment mechanism also includes two lifting clamps 206 that are slidably mounted on the guide clamp 201. The lifting clamps 206 and the two sections of the lifting screw 204 form a threaded transmission. An adjustment motor 207 is fixedly mounted on the lifting clamps 206. An adjustment gear 208 is fixedly mounted on the motor shaft of the adjustment motor 207. An adjustment roller 209 is rotatably mounted on the lifting clamps 206. A rotating roller gear 211 is fixedly mounted on the adjustment roller 209. The rotating roller gear 211 meshes with the adjustment gear 208. An outer rubber sleeve 210 is provided on the outside of the adjustment roller 209.
[0028] After the two gripper modules lift the H-shaped column from the truck, the extension cylinder 103 retracts, causing the extension gripper frame 104 and the gripping gripper 109 to move inward, so that the H-shaped column is between the two outer rubber sleeves 210 which are in the open state. Then, the lifting motor 202 drives the output gear 203 to rotate, which drives the lead screw gear 205 and the lifting lead screw 204 to rotate. The lifting lead screw 204 drives the two lifting clamps 206 to move towards the H-shaped column at the same time through the threaded transmission. Then, the outer rubber sleeves 210 fit against the side of the H-shaped column.
[0029] Once the H-shaped column is in an upright position, the stabilizing mechanism is released, and the adjusting motor 207 drives the adjusting gear 208 to rotate, which in turn drives the rotating roller gear 211, the adjusting roller 209, and the outer rubber sleeve 210 to rotate. The rotation of the outer rubber sleeve 210 causes the H-shaped column to move downward, so that the H-shaped column is inserted into the ground at the installation location, thus realizing the installation of the H-shaped column. During the process of moving the H-shaped column downward through the outer rubber sleeve 210, the lifting motor 202 also rotates, causing the two lifting clamps 206 to move inward simultaneously, ensuring the slow and stable installation process of the H-shaped column.
[0030] like Figure 9 , Figure 10 As shown, the stabilizing mechanism includes two fixed rotating blocks 301 fixedly mounted on the main clamping frame 101. A rotating clamping frame 303 is rotatably mounted on the fixed rotating blocks 301. A rotating frame gear 302 is fixedly mounted on the rotating clamping frame 303. Two clamping motors 306 are fixedly mounted on the fixed rotating blocks 301. A clamping gear 307 is fixedly mounted on the motor shaft of the clamping motor 306. The clamping gear 307 meshes with the rotating frame gear 302.
[0031] like Figure 9 , Figure 10 As shown, the stabilizing mechanism also includes two clamping rollers 304 rotatably mounted on the rotating clamp 303, and an outer friction sleeve 305 is sleeved on the outside of the clamping rollers 304.
[0032] When the extension cylinder 103 retracts, the H-shaped column reaches between the two outer rubber sleeves 210 in the open state. At the same time, the H-shaped column also reaches between the two outer friction sleeves 305 of the same stabilizing mechanism. At this time, the outer friction sleeves 305 do not contact the H-shaped column, and the side of the H-shaped column is equidistant from the two outer friction sleeves 305. Subsequently, the clamping motor 306 drives the clamping gear 307 to rotate. The clamping gear 307 drives the rotating frame gear 302 and the rotating clamp 303 to rotate. The rotation of the rotating clamp 303 drives the separate clamping roller 304 and the outer friction sleeves 305 to rotate, so that the two outer friction sleeves 305 simultaneously contact the side of the H-shaped column, and the outer friction sleeves 305 undergo a certain deformation. The two outer friction sleeves 305 apply clamping forces of the same magnitude but opposite directions to the surface of the H-shaped column, enhancing the stability of clamping the H-shaped column.
[0033] The working principle of the railway catenary H-type column installation clamp disclosed in this invention is as follows: During use, the connecting end block 102 is installed at the end of the excavator's robotic arm. The inlet and outlet oil pipes 108 and the extension cylinder 103 are connected to the excavator's hydraulic system, and power is simultaneously drawn from the excavator. First, the excavator moves to the side of the freight car equipped with the H-type column. At this time, the H-type column is in a flat position. The excavator uses its robotic arm to bring the connecting end block 102 and the main clamping frame 101 to the side of the flat H-type column. Subsequently, the two output ends of the clamping cylinders 107 of the two gripper modules retract, driving the inner side of the clamping gripper 109 to move inward. The inner movable block 106 slides along the side guide block 105, causing the clamping gripper 109 to move inward. The cylinder 103 extends, causing the extension claw 104 and clamping claws 109 to move outward, so that the outer ends of the two clamping claws 109 reach the outside of the H-shaped column. Then, the two output ends of the clamping cylinder 107 extend, causing the outer ends of the clamping claws 109 to move inward, so that the two clamping claws 109 clamp the H-shaped column. Since the sides of the cement column 4 and the steel column 5 are conical and pyramidal surfaces, the two clamping claw modules clamp the cement column 4 and the steel column 5 at two points to ensure the stability of the clamping. Since the sides of the cement column 4 and the steel column 5 are conical surfaces, the opening and closing degrees of the clamping claws 109 of the two clamping claw modules are not the same.
[0034] After the two gripper modules lift the H-shaped column from the truck, the extension cylinder 103 retracts, causing the extension gripper frame 104 and the gripping gripper 109 to move inward, so that the H-shaped column is between the two outer rubber sleeves 210 which are in the open state. Then, the lifting motor 202 drives the output gear 203 to rotate, which drives the lead screw gear 205 and the lifting lead screw 204 to rotate. The lifting lead screw 204 drives the two lifting clamps 206 to move towards the H-shaped column at the same time through the threaded transmission. Then, the outer rubber sleeves 210 fit against the side of the H-shaped column. When the extension cylinder 103 retracts, the H-shaped column reaches between the two outer rubber sleeves 210 in the open state. At the same time, the H-shaped column also reaches between the two outer friction sleeves 305 of the same stabilizing mechanism. At this time, the outer friction sleeves 305 do not contact the H-shaped column, and the side of the H-shaped column is equidistant from the two outer friction sleeves 305. Subsequently, the clamping motor 306 drives the clamping gear 307 to rotate. The clamping gear 307 drives the rotating frame gear 302 and the rotating clamp 303 to rotate. The rotation of the rotating clamp 303 drives the separate clamping roller 304 and the outer friction sleeves 305 to rotate, so that the two outer friction sleeves 305 simultaneously contact the side of the H-shaped column, and the outer friction sleeves 305 undergo a certain deformation. The two outer friction sleeves 305 apply clamping forces of the same magnitude but opposite directions to the surface of the H-shaped column, enhancing the stability of clamping the H-shaped column.
[0035] After the H-shaped column is clamped by the gripper module, the excavator's robotic arm lifts the H-shaped column from the truck. The excavator then moves the H-shaped column to the installation site. The inner brake 114, which is in a locked state, is then activated, allowing the brake disc 113 to rotate. The rotating motor 110 drives the motor gear 111 to rotate, which in turn drives the center gear 112, the brake disc 113, and the main clamping frame 101 to rotate 90 degrees, making the H-shaped column vertical. The inner brake 114 then locks the brake disc 113 again. Once the H-shaped column is in an upright position, the stabilizing mechanism is released, and the adjusting motor 207 drives the adjusting gear 208 to rotate, which in turn drives the rotating roller gear 211, the adjusting roller 209, and the outer rubber sleeve 210 to rotate. The rotation of the outer rubber sleeve 210 causes the H-shaped column to move downward, so that the H-shaped column is inserted into the ground at the installation location, thus realizing the installation of the H-shaped column. During the process of moving the H-shaped column downward through the outer rubber sleeve 210, the lifting motor 202 also rotates, causing the two lifting clamps 206 to move inward simultaneously, ensuring the slow and stable installation process of the H-shaped column.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
